(54) Title: BLOCKCHAIN DATA STORAGE BASED ON ERROR CORRECTION CODE FOR PERMISSIONED BLOCKCHAIN 
NETWORK 
(57) Abstract: Disclosed herein are methods, systems and apparatus, including 
computer programs encoded on computer storage media, for storing blockchain 
data. One of the methods includes receiving transactions issued by a client 
60~4 606 68 600 node communicably coupled to a permissioned blockchain network, sending the 
/ transactions to a plurality of validating nodes for validating the transactions and 
running consensus, receiving one or more blocks generated based on consen
-sus ofat least aportion of the transactions by the plurality of validating nodes, 
encoding the one or more blocks using ECC to generate one or more encoded 
blocks, and for each encoded block of the one or more encoded blocks: dividing 
610 the encoded block into a plurality of datasets based on a data storage scheme 
602 -N associated with the one or more blocks.
